She was my once-in-a-lifetime
Happy ending come true
I guess I should have told her
I thought she knew

She said I took her for granted
It's the last thing I would do
Oh, I'll never understand it
I thought she knew

I thought she knew my world revolved around her
My love light burned for her alone
But she couldn't see the flame
Only myself to blame
I should have known
I should have known

A heart full of words left unspoken
Now that we're through
I tell my soul to have its silence broken
I thought she knew, I thought she knew

I thought she knew my world revolved around her
My love light burned for her alone
But she couldn't see the flame
Only myself to blame
I should have known
I should have known

She was my once-in-a-lifetime
Happy ending come true
Oh, I guess I should have told her
But I thought she knew (I thought she knew)

I thought she knew
I thought she knew
Ooh
I thought that she knew
